Methodology
How RootFetch computes delegation intelligence.
- Primary count metric:
count_ns_sld, delegated SLD-owner count inferred from NS records. - Baseline mode: full approved-TLD sweep to establish complete coverage.
- Hybrid mode: core daily recounted + rolling deterministic long-tail refresh.
- Snapshot rows keep full visibility; observed rows track what was freshly recounted today.
Conceptual Data Flow
CZDS approved list -> local baseline/hybrid recount -> daily_counts + growth_trends -> signals (market + trend + coverage) -> digest + static RAG -> committed artifacts -> read-only Vercel + MCP
Distribution
Cross-sectional shape of delegated counts today.
p50/p90/p99 summarize spread. Tiny and small buckets show long-tail breadth.
Concentration
How much delegated volume is held by largest TLDs.
Top1/Top3/Top10 shares and HHI quantify concentration. Higher HHI indicates stronger concentration.
